It is ideal for demanding desktop applications requiring the maximum in I/O expansion flexibility. A 60 MHz or 66 MHz Pentium microprocessor is complemented by a 256 KB second level write-back cache to provide workstation- level computing performance. A Pentium OverDriveä socket provides access to future performance enhancements, and SIMM sockets support up to 128 MB of system memory. The Premiere/PCI Baby-AT motherboard offers outstanding I/O capabilities. Three PCI local bus slots provide a high bandwidth data path for data-intensive functions such as graphics and disk I/O. Integrated peripherals include the RZ1000, which provides a PCI local bus primary IDE interface, as well as the SMC 37C665 Super I/O component, which provides floppy and secondary IDE drive interfaces, two FIFO serial ports and an ECP-capable parallel port. Five ISA slots complete the I/O mix. STANDARD BABY-AT FORM FACTOR The Premiere/PCI Baby-AT motherboard conforms to the industry standard Baby-AT form factor. It meets the specifications for maximum board size, board mounting locations, expansion slot placement, and keyboard connector location. In addition to complying to the standard, the Premiere/PCI Baby-AT provides three slots which will accommodate PCI expansion cards. 13.0" 0.5" 12.6" 5.6" 6.6" 0.5" 0.3" 5.6" 8.6" Figure 1.

Premiere/PCI Baby-AT Motherboard components CPU The Premiere/PCI Baby-AT motherboard is designed to operate with either a 60 MHz or 66 MHz Pentium microprocessor. This processor is compatible with the 8086, 80286, i386ä and i486ä CPUs. It supports both read and write burst mode bus cycles, and includes an on-chip 16 KB cache which is split into 8 KB code and 8 KB data caches employing a write-back policy. The Pentium processor also integrates an advanced numeric coprocessor which significantly increases the speed of floating point operations, while maintaining compatibility with i486äDX math coprocessors and complying with ANSI/IEEE standard 754-1985. Premiere/PCI Baby-AT motherboards equipped with 66 MHz Pentium processors have a voltage control circuit that regulates Vcc to the CPU and frequency synthesizer. The voltage regulation accomodates a variety of Intel CPUs and increases the overall robustness and reliability of the motherboard. Boards without the voltage regulator circuitry cannot reliably use 66 MHz Pentium processors. The motherboard contains two mounting holes which allow a dedicated fan to be located directly in front of the CPU socket. A 12 volt connector suitable for a CPU fan is located close to the mounting holes. PERFORMANCE UPGRADE A 273-pin Type 4 Zero Insertion Force socket provides users with a performance upgrade path using Pentium OverDrive processors. The OverDrive processor being developed for use in this socket will provide performance beyond that delivered by the Pentium microprocessor. SECOND LEVEL CACHE The Pentium processor's internal cache is complemented with a 256 KB direct mapped, write-thru second level cache implemented with eight 32Kx8, 15 ns SRAM devices. Tag and control logic is contained in the 82434LX PCMC core chip. Premiere/PCI Baby-AT Technical Product Summary · Page 6 SYSTEM MEMORY The Premiere/PCI motherboard provides four 72-pin SIMM sites for memory expansion. The sockets support 256K x 36 (1 MB), 512K x 36 (2 MB), 1M x 36 (4 MB), 2M x 36 (8 MB), 4M x 36 (16 MB), and 8M x 36 (32 MB) SIMM modules. Minimum memory size is 2 MB and maximum memory size, using four 8M x 36 SIMM modules, is 128 MB. Memory timing requires 70 ns fast page devices. Parity generation/checking is provided for each byte. Non-parity 32 bit SIMMs also may be used, in which case the parity generation/checking circuitry is automatically
